    In this summer's heat I need clothes cooler than cotton - and these Terramer Helix T-shirts are just the trick.

    They feel better than cotton - and look better than cotton.

    Wish I'd had them years ago.

    I will disagree with one other reviewer's disagreement. These shirts DO run about one size too small, so order up. According to the tag, they have "EC2 Quik-Dri technology", which supposedly gives the shirt the ability to lift moisture molecules away from the skin, breaking them down for rapid evaporation - apparently a patented process that is permanently embedded in the fabric, and which does not wash or wear out of the fabric. I was a little concerned that the shirts would not be stretchy, but they do have a nice bit of stretch so they move with your body.

    As for EC2, on an initial trial run walking the dog in very hot and humid conditions, the shirt does feel drier when sweating. It will be interesting to see how effective it is in heavy sweating conditions, but I would assume it will perform better than CoolMax or other fabrics. I will need more time to verify this. These shirts are very light in weight and would be popular with Appalachian Trail through-hikers or other distance backpackers looking to keep their weight down. As for me, this shirt will serve me well for hiking, backpacking, yard work and other functions. And they do have Anti Microbial to keep odors down, unlike a Reebok shirt I own which seems to hold on to odors.

    All in all, a nice shirt for the money. The somewhat open weave and light weight may make them more prone to "picking", but most of my other performance shirts are at risk of this as well. I would recommend this shirt it to friends.

    Why go to a department store or large sporting goods store and spend $20+ on a similar shirt?

    Lightweight, breathes exceptionally well, and fits as it should. This makes a great workout shirt - no need to spend more than 10 bucks for that.

    Another reviewer rated this "runs large" and "order size smaller". Not so, causing me to return my order and reorder next size up. Great price and thanks for the second order discounted shipping fee. This shirt is top-of-the-line as your gym and running shirts at a fantastic price.

    • Answer Very true. I was in the same boat and I took two things into consideration. First, I didn't mind if the shirt was a bright blue (really a dark bright blue, if that makes sense), so I thought I would gamble and see if it really was purple, like in the picture. It isn't. Secondly, these shirts are an absolute steal at this price for a moisture wicking shirt, so it wasn't that big of a deal to me. I didn't get a purple shirt like the picture, but I got a nice blue shirt like advertised.

    • Answer Always read description carefully especially on closeout items! perhaps the company didn't have correct color swatch to display, but I do like the performance of these shirts.

    • Answer Sorry, I have purchased neither color. That said, what I have purchased made by this brand has been first class. My favorites are the Dri-Release shirts;
      very comfortable.

    • Answer A long sleeve that I bought looked like a cool almost pink color, but when I got it, it was an orange tee. That specific color I did buy and on my monitor it did look purple but like you said the color description was blue.

    • Answer Hi...I don't remember doing a review on these, but I can tell you that the Brick is definitely not green. It is a red-like color with rust shade (a bit like a muted orange/red). Good luck!
      Answered on 3/27/2015 11:37:29 AM by Momika from Idaho
    • Answer Just checked out the color samples of this fantastic t-shirt. Cypress is typically light blue (not listed in samples).
      Brick appears to be a dark orange/pale red. By the way, nice choice of T-shirt. I bought several of these, my husband loves them.

      Hope this helps.

    • Answer Well, I got one in steel blue and its a little lighter than the color on the website. But for your case, I'd say the brick does look like a dark orange-red. But if it looks like the cypress to you, then get the brick! I'm not sure if this is helpful for what you're asking, but I hope so!
      Answered on 3/27/2015 1:15:11 PM by Larbo6 from Oklahoma
    • Answer In taking a look at the colors, it appears to me that the color brick looks more like a copper color or more dark orange. So neither red or green. The lava color looks brighter orange than the bright orange color, and the bright orange color looks red. So it would appear that the people at Terramar could be color blind too. I hope this helps.
      Answered on 3/27/2015 8:51:39 PM by telern from Front Range, [...]
    • Answer There is no "Cypress" color option for this tee. If you mean "Citrus," I find it to be an unappetizing shade of green. I greatly would prefer "Olive." On the other hand, "Brick" is a darker shade of "Orange"--an entirely different color than "Citrus." I do things the easy way, wearing "Black" only. Do not know if this piece of information is of any use to you, but the easiest way by far to remember the colors of the spectrum is to memorize the name of Mr. Roy G. Biv--red, orange, yellow, green, blue, indigo, violet. All shades of color derive from these "majors." White is the absence of color. Black is, well, I forgot that part of my junior-high-school chemistry class....

    • Answer Hello,

      I am not aware that there is a "cypress" color for this shirt. There is a "citrus" which is a sort of lime green, however, I am not seeing "cypress as a color option.

    • Answer the brick color on the website looks a little Red/Orange, but I would imagine to usually mean red. It may look more red than the web photo, but I would guess cypress to be green. Hope this helps

    • Answer The Brick is an ORANGE/RED color, it is a deep reddish/orange hue. Hope this helps. My husband LOVES this shirt, it s light weight, and really does whisk the perspiration away. He wore it in the Caribbean on a hike to the top of one of the Mayan Ruins, a strenuous hike.

    • Answer I bought one in a ladies size for my wife (different catalog nunmber). It is very form-fitting, but she described it as true to size otherwise. The man's XL fit is snug on me, too, but that's the way many wicking shirts are designed. Hope that helps.

    • Answer The T-shirt prevents moisture build up and therefore will dry quicker than a normal shirt.

    • Answer Dear Pedro, I think these will do well you. They do dry quickly because of the open weave, but still trap some heat d/t being more porous next to the skin. Best.
